Every two years to be safe

Very good-with the exception of the oil sensor mounted on the engines-I have twins and they have failed to often.

How often should the oil be changed in a Honda CR 125 R two stroke motorcycle?

There is no such thing as engine oil changes in two stroke motorcycle engines. The two stroke oil serves to lubricate the engine as it is mixed with gasoline. For the gearbox, on the average a yearly change of gear oil is sufficient.


What are the names of the strokes on a two stroke engine?

A two-stroke engine is an internal combustion engine that completes the process cycle in one revolution of the crankshaft (an up stroke and a down stroke of the piston, compared to twice that number for a four-stroke engine). This is accomplished by using the beginning of the compression stroke and the end of the combustion stroke to perform simultaneously the intake and exhaust (or scavenging) functions. In this way, two-stroke engines often provide strikingly high specific power, at least in a narrow range of rotational speeds. The functions of some or all of the valves required by a four-stroke engine are usually served in a two-stroke engine by ports that are opened and closed by the motion of the pistons, greatly reducing the number of moving parts.


Is a 15 hp gamefisher 2 stroke or 4 stroke?

A 15 hp game fisher motor is most often a 2 stroke engine. However there can also be a 15 hp game fisher motor that is a 4 stroke as well.


Is a Suzuki lt185 2 stroke?

i have an 84 suzuki lt 185 quad, it is 4 stroke. so, "no" to your answer one way to see if something is 4 stroke is look on the engine, if it has ridges it is four stroke these are vents 2 strokes dont need them because they are often liquid cooled. another way to find out is a 2 stroke will have a big head pipe for that added "kick" a two stroke has over a 4 stroke. a two stroke often has a higher pitch (more annoying) noise, where a 4 stroke often has more of a low pitch dull sound to it (its alot more quiet).


What if you dont use stihl geniune two stroke mix what would the ratio be for regular two stroke mix?

Most oils nowadays are 50:1. The great thing now is that an air cooled engine two cycle oil often comes in a package that mixes a gallon of gas to the correct amount. Beware of outboard motor oil as those engines are water cooled, not air cooled (heat is different.)


What is a power reed?

2 stroke engine power reed info: (works on outboard engines/ motorbikes, mowers & my brush cutter. hope this helps (google- boysen reeds) Reeds are one-way valves controlling the amount of air/fuel mixture entering the crankcase of your outboard engine, then sealing it in to prevent it from escaping. Every two-cycle outboard has them. But the stock reeds in your outboard have a single-stage design that limits their efficiently. That's why stock outboards often cough and sputter at idle, fail to deliver a good hole shot, feel boggy or lifeless under throttle application, burn too much fuel or lack top-end punch. Plus, standard reeds are made of metal. Should one break, it could cause extensive damage to your outboard.


Advantages of a 2 stroke?

-Low maintainence(no crank case oil to change or valves to set) -Simple in design (VERY easy to rebuild) -The ability to rev much higher than a 4-stroke(less minor shifting) -Impressive "snap" during the power band -Much less moving parts than a 4-stroke A 2-stroke engine fires on every complete engine cycle giving it, in theory, twice the power of a 4-stroke. Unfortunately, due to the engine design restrictions, the 2-stroke's power only becomes available at higher RPMs. At low RPMs 2-stroke engines are clunky and gutless. So, if you ride aggressive, your always on the throttle, you need that quick pick up often, you will benifit from it.


How often do you get an engine flush?

I do it befor every oil change, and my engine is very silent


How often do you need to change your oil in your KX125?

I still run a 2 stroke and change gear oil every 5 hours of riding time.
